ROBERT BUTCHER, OF JOLIET, ILLINOIS.

DUMP-GAR.

Application filed May 25, 1920.

To all whom it may concern Be it known that I, ROBERT BUTCHER, a citizen of the United States, residing at .loliet, in the county of .Vill and State of Illinois, have invented new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to dump cars having a hopper bottom, and its object is to provide a novel and improved arrangement of gates and doors therefor, for discharging the contents of the car, slidable end gates and swinging side doors being provided, with a connection therebetween whereby they are operated simultaneously.

The object stated is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawings forming a part of this specification.

In the drawings,

Figure l is a side elevation of the car;

Fig. 2 is a central longitudinal section of the hopper bottom;

Fig. 3 is a plan view thereof;

Fig. 4 is a cross-section on the line 4-4 of Fig. 2;

Fig. 5 is an end view of the hopper bottom, and

Fig. 6 is an elevation showing an auxiliary operating means.

Referring specifically to the drawings, the invention is shown applied to a type of dumping car having a hopper bottom. The sides 10 of the car are straight, and the ends 1.1 extend straight down from the top for a short distance and from said ends inclined bottoms 12 extend. A longitudinal rib or beam 13 braces the center of the car and from the same extend laterally inclined floors or bottoms 14 functioning to deflect the material laterally to the respective sides of the car after it slides down the inclined bottoms 12, the latter having continuations in the form of slides 15 filling the space toward the bottom center of the car. The slides 15 form end gates for the hopper bottom and they can be drawn outwardly, or apart, by operating rods 16 extending from pistons working in cylinders 17 fed from the air line 18. The slides 15 are recessed, as shown at 19, to clear the cylinders 17, and they are also recessed, as shown at 20, to

clear the rib or beam 13. The side edges of the slides 15 work in guide strips 21.

The side walls 10 of the car have bottom extensions 22 hinged to said walls, as shown at 23, and forming doors for the sides of the hereinbetore described hopper bottom. The doors 22 are opposite the inclined bottoms 14, and they are adapted to be swung outwardly, as shown dotted in Figs. 4 and 5, and when so swung the material is discharged sidewise in an obvious manner.

The doors 22 are opened automatically by the outward movement of the slides 15, there being provided an actuating connection between said parts. This connection comprises thrust links-2 1 which are connected at one end to the slides 15, as shown at 25, and at their other ends to the doors 22, as shown at 26. The links 24 are so positioned that they extend obliquely between the points 25 and 26 when the parts 15 and 22 are closed. It will therefore be seen that when the slides 15 are moved upwardly (see Fig. 5), the links 24: tend to assume a horizontal position, and they thus act similar to a toggle to thrust the doors 22 open.

The end gates or slides 15 may also be operated manually by providing the same with racks 27 operable by pinions 28 equipped with crank handles 29. This auxiliary operating means is shown in Fig. 6, and it is intended to be used on failure of the air system.

I claim:

1. A dump car having end discharge gates and side discharge doors, the gates being slidable up and down and the doors being pivoted to swing laterally of the car, operat ing means for the gates, and actuating connections between the gates and the doors.

2. A dump car having end discharge gates and side discharge doors, the gates being slidable up and down and the doors being pivoted to swing laterally of the car, operating means for the gates, and actuating connections between the gates and the doors, said connections comprising thrust links connected to the gates and the doors, and eX- tending obliquely therebetween.

3. A dump car having a hopper bottom the floor of which inclines in opposite directions from the longitudinal center line of the car, and the ends of the hopper also having a downward incline toward each other, slidable gates associated with said inclined ends, side doors for the hopper pivoted to vswing laterally of the car, operating means and side discharge doors, the gates being slidable up and down and the doors being pivoted to swing laterally of the car, and actuating connections between the gates and the doors whereby the same are simultaneously operated.

5, dumpcar having a hopper bottom the floor of which inclines in opposite directions from the longitudinal center line of the car, andthe; ends of the hopper also having a downward incline toward each other, slidable gates associated with said inclined ends, side doors for the hopper pivoted to swing laterally of the car, and actuating connections between the gates and the doors whereby the same are simultaneously operated.

6. A dump car having end discharge gates and side discharge doors, the gates beingslidable up and down and the doors being pivoted to swing laterally of the car, and actuating connections between the gates and the doors whereby the same are simultaneously operated, said connections comprising thrust links connected to the gates and the doors, and extending obliquely therebetween.

In testimony whereof I afiix my signature.
